mergeObject ob1,ob2… Merge object, deep clone
getApp Same as wechat official getApp
getCurrentPages Same as wechat official getCurrentPages
getCurrentPage Get current page
getCurrentPath Gets the current page path
getPath targetPath A simple encapsulation of getRelativePath that doesn’t require the current path, just the destination path
getRelativePath currentPath,targetPath Gets the relative path between two paths
getTimestamp Get timestamp
getClassName The object key corresponds to class, and the value corresponds to true or false The method of obtaining class, using the same method as ng, more convenient generation of class

import utils from './utils/index';
 
App({
  onLaunch() {
    this.utils = new utils()
  }
})
